Network Protocols: Network protocols are sets of rules and standards that govern communication between devices on a network. They ensure that data is transmitted efficiently and accurately. Common Network Protocols: 1. TCP/IP (Transmission Control Protocol/Internet Protocol): A suite of protocols that governs the internet. 2. HTTP (Hypertext Transfer Protocol): Used for web communication. 3. FTP (File Transfer Protocol): Used for file transfer. 4. DNS (Domain Name System): Translates domain name
